IMPROVEMENT m oooR-RETAmERs.

Specification forming part of Letters Patent No. [86,319, dated January16, 1877; application. filed December 20, 1876.

Be it known that I, Bonner E. Dm'rz, of New York city, State of NewYork, have invented a new and useful Improvement in Door-Retainers, ofwhich the following is a specification The object of my invention is tomake a device which, in conjunction with the knob of an ordinarydoor-latch, will serve to retain the door, and at the same time permitit to be opened to an extent sufficient to permit a conversation betweenparties on opposite sides of the door; and this objectl attain by meansof a looped chain, covered with soft material, and fastened to thedoor-frame, the loop being applied to the knob of the door.

In the accompanying drawing, Figure 1 represents my improveddoor-retainer, and Fig. 2 a modification of the same.

A chain, A, composed of links of any desired construction, has at eachend an eye, a, for the reception of a screw, b,which serves to securethe said two ends of the chain to the frame of the door in a positionadjoining the ,knob B of the usual latch-bolt. The chain thus secured tothe doorframe forms a loop long enough to be passed over the handle, onthe neck of which it can rest, as shown by dotted lines in Fig. 1.

While the loop of chain should be short enough to eflectually preventthe wide opening of the door, it should be sufliciently long to allow aslight opening, large enough to perwit a conversation between parties onopposite sides of the door.

I preferto cover the chain with soft yield ing material.

Leather, for instance, will serve the purpose but the chain may be mosteasily clothed with rubber by introducing it into a tube, D, of thatmaterial.

The object of this soft clothing of the chain is threefold first, itretains the loop of chain in a proper distended condition for readyapplication to the knob; second, it prevents .the disagreeable rattlingof the chain and, third, it prevents the abrasion of the neck of theknob by the chain.

'When the retainer is not in useit may be hung down, as shown in thedrawing. so as to be clear of the edge of the door. (Represented by theline as an.)

The loop or chain may be made as shown in Fig. 2, which will be readilyunderstood without explanation in fact the chain may be arranged indifferent ways, providing it be constructed for attachment to thedoor-frame,

and for application to the knob in the manner described.

I claim as my invention- The within-described door-retainer, consistingof a looped chain covered with rubber or other soft material, andattached to a doorframe, the loop being adapted for application to theknob of the door, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ROBERT E. DIETZ.
